Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031242, here are decompositions:

11 + 1031231 = 1031242
53 + 1031189 = 1031242
101 + 1031141 = 1031242
239 + 1031003 = 1031242
293 + 1030949 = 1031242
353 + 1030889 = 1031242
419 + 1030823 = 1031242
431 + 1030811 = 1031242

Showing the first eight; more decompositions exist.
